UI editor relies on Z-Index even though screengui ZIndexBehaviour is set to Sibling

[Fifkee (Noire)]

I believe this change was recent as well as this wasn’t happening last time I edited a UI object through click and drag.

Reproduction is simple:

1. Create a frame in a ScreenGui, rather, any 2D object for that matter and set it to Z-Index 400
2. Place any other Gui inside of the previously created frame without modifying it’s Z-Index
3. Try to select the Gui inside of the frame. You instead grab the first frame even though your ScreenGui’s ZIndexBehaviour is on Sibling.
4. Now try setting the second frame’s Z-Index to 401 and try grabbing it. What do you notice? You can all of a sudden grab the frame again even though it’s clear that it’s displayed over the first frame.

You should be able to grab the highest frame, not whatever is under it.

Hi Fifkee. Thanks for the report, we will look into this.

I have been told by the engineers that a fix for this issue has been worked on and should be rolled out early next year. When/if there is more information I will pass it on.
